There are a fair number of businesses in old industries that "went digital" 10-20 years ago still have the same tech running, including FTP. I work with a company that requires uploading files via FTP into a co-mingled directory (everyone uses the same password). Company is a major player in my industry, too.

I would be curious if some government services were still running FTP, judging by the number of Y2K-era government websites I run into.
